NITED STATE FEEDING ATTACHMENT.

Application filed April 5, 1922.

To all whom it may concern:

Be it known that I, LAWRENCE B. GRAS- BERGER, a citizen of the UnitedStates, residing at the city of Richmond, in the State of Virginia, haveinvented certain new and useful Improvements in Feeding Attachments, ofwhich the following is a specification.

This invention relates to feeding attachments for roll holders used instores for supplying wrapping paper in sheets as required; and itconsists in the novel construction and combination of the partshereinafter fully described and claimed, whereby the paper roll isrevolved a little so as to make. the free end portion of the paperprotrude below the tearing-off blade, where it can be grasped by hand,and simultaneously to raise the blade clear of the paper.

In the drawings, Figure 1 is a front view of the upper part of a rollholder provided with a feeding attachment according to this invention.Fig. 2 is an end view of the attachment drawn to a larger scale andshowing the blade in section, and with the feed roller pressed againstthe roll. Fig. 3 is a front view of the parts as shown in Fig. 2.

The feeding attachment can be applied to many makes of roll holders,both horizontal and vertical. In the example shown, the roll of paper 6is horizontal, and it is journaled in a frame 7. A blade 8 is secured toarms 9, and bears on the periphery of the roll. The arms are pivoted tothe frame by pins 10, and the paper is torn off against the bottom edgeof the blade. The roll requires to be revolved a little after a sheet ofpaper has been torn from it, so that the loose end of the paper can begrasped by hand.

A. bracket 12 is pivoted to the blade 8, and projects upwardly of theblade at the middle part of its length. The lower part of the bracket ispreferably pivoted by a pin 11 to a hinge plate 15 which is secured tothe blade. and the plate 15 has a stop lug 16 which bears against thebracket and prevents it from being moved too far away from .the roll. Aspring 17 is provided for pressing the bracket away from the stop lug,and any kind of a spring may be used for that purpose.

A pivot roller 18 is j ournaled in the frame adjacent to the hinge pin14, and it and the Serial No. 549,864.

blade are normally held in contact with the roll of paper. A feed roller20 is journaled in the upper part of the bracket, on the other side ofthe pivot roller from the hinge pin, and is preferably a wooden rollercovered with india rubber.

After a sheet has been torn from the roll, the roller 20 is pressed byhand against the roll, and is revolved by the hand in the direction ofthe arrow in Fig. 2. This raises the blade clear of the roll, and turnsthe roll so that the loose end 21 of the paper can be grasped withfacility.

What I claim is:

1. The combination, with a frame for supporting a roll, and a bladepivoted. to the frame and adapted to bear on the roll; of a bracketpivoted to the blade and projecting upwardly of it, a pivot rollerjournaled in the bracket, and a feed roller journaled in the bracketabove the pivot roller and normally supported clear of the roll, thesaid blade being raised clear of the roll when the feed roller ispressed against the roll.

2. The combination, with a frame for supporting a roll, and a bladepivoted to the frame and adapted to bear on the roll; of a bracketpivoted to the blade and projecting upwardly of it, a pivot rollerjournaled in the bracket, a spring which normally holds the pivot rollerin contact with the roll, a stop which limits the movement of the saidbracket away from the roll, and a feed roller journaled in the bracketabove the pivot roller and normally supported clear of the roll, thesaid blade being raised clear of the roll when the feed roller ispressed against the roll.

3. The combination, with a frame for supporting a roll, and a bladepivoted to the frame and adapted to bear on the roll: of a hinge platesecured to the said blade, a bracket pivoted to the upper edge of thehinge plate, a pivot roller journaled in the lower part of the saidbracket. means for holding the pivot roller in Contact with the roll,and a feed roller journaled in the upper part of the bracket andsupported clear of the roll while the said blade is in contact with theroll.

In testimony whereof I have aiiixed my signature.
